Alas, poor Amtor

Trivia fact: Edgar Rice Burroughs, in addition to his Tarzan and Mars books, also wrote a handful of pulp stories about Venus, which was called Amtor by the natives, and his intrepid hero, Carson Napier. They were a little different from the Mars series, where John Carter was teleported to Mars by some form of astral projection, in that Napier was a rocket pilot flying to Mars who made a tiny error in his calculation and crash-landed on Venus instead. Then it lapses into the usual formulaic adventure story where Napier finds a Princess (there’s always a princess), falls in love, and the two of them bumble about needing to rescue each other from pirates and communists. Amtor, by the way, is covered by oceans and continents of giant trees, and the cloud cover keeps the planet cool and liveable, except when the clouds briefly break and a brutal sun sets everything on fire beneath the gap.

Unfortunately, the real Venus has surface temperatures of 450°C and a dense and acidic atmosphere. Nothing lives there.

This recent modeling of the Venerian atmosphere suggests that there may have been a long period of relative coolth in the planet’s history. The runaway greenhouse effect wouldn’t have occurred until a period of intense volcanic activity that produced LIPs, Large Igneous Provinces, released even more CO2, and then the temperatures soared.

That surge occurred less than a billion years ago, so it’s easy to imagine warm (mean temperature of around ~20°C, compared to Earth’s current ~15°C) oceans in which life could have evolved before global warming slammed the hammer down and burnt the soup.

I think Carson Napier’s navigation error had to have been off by more than I thought: 150 million kilometers and a billion years. Even then he wouldn’t have found princesses, but at best the equivalent of single-celled prokaryotes, which would have been far more interesting than mere Amtorian princesses.

My summer fantasy

Here’s what I do for a little relaxation: I stare at maps. My summer research is a bit constrained right now, so I’ve been planning alternatives, like making day-trips to neglected local spots to do spider-hunting. I will be the first to admit that my knowledge of spiders is limited — I know a fair bit about a few species that live in the niches I’ve concentrated on, but relatively little about a lot of species that are in other environments. I need to correct that.

So I’ve been looking at maps and planning lovely little trips. My wife and I will pack the car with a picnic lunch, collecting tubes, my camera, and a drone (for scouting out locations), we’ll dress in long pants and long sleeves and boots, douse ourselves with DEET, and take off in the morning for a leisurely drive with frequent stops. We’ll look for parks and lakes and streams and abandoned farms and tromp around looking for spiders, photographing many, capturing a few, and heading back home in the late afternoon.

It sounds delightful to me. Right now all I can do is look at maps and plan these jaunts until I get all my grades submitted and recover my faithful companion, but it’s nice, and perfect for the pandemic season, because I plan to avoid people and visit places that spiders would like, and spiders don’t carry the virus. I look at the roads and the satellite views that reveal brushy areas where no one in their right mind would want to go — well, some of them might look great to hunters and fisherpeople, and that’s OK, I can share — and look forward to getting dirty and scratched and bug-bitten.

I also keep an eye on the local news. Oh, the Grass Lake restoration project is winding up? I bet there are spiders there. The university is constructing an ecostation? Spider country!

My original plans for the summer were a bit more lab-centered, and I still have some lab projects to maintain, but I’ve been thinking about how to adapt to our new circumstances, and I think I can find happiness in a summer in the weeds.

If the virus were the size of dinosaurs, maybe people would appreciate the danger

This story is a bit on the nose.

Hello, Peter Ludlow here, CEO of InGen, the company behind the wildly successful dinosaur-themed amusement park, Jurassic Park. As you’re all aware, after an unprecedented storm hit the park, we lost power and the velociraptors escaped their enclosure and killed hundreds of park visitors, prompting a two-month shutdown of the park. Well, I’m pleased to announce that, even though the velociraptors are still on the loose, we will be opening Jurassic Park back up to the public!

I mean, it really hammers on the comparison. You can’t miss it. No one will accuse it of subtlety.

As some of you know, Dr. Ian Malcolm, our lead safety consultant, had recommended that we wait until the velociraptors have been located and contained before reopening the park, so he wasn’t thrilled when we told him the news. I believe his exact words were “you were so preoccupied with whether you could reopen the park, you didn’t stop to think whether you should.” Talk about a guy on a high horse.

That said, you’ll be pleased to know that, rather than double down on our containment efforts, we’ve decided to dissolve the velociraptor containment task force altogether, and focus instead on how we can get people back into the park as quickly as possible. So rather than concentrating on so-called life-saving measures like “staying in designated safe areas” or “masking your scent,” we’ll be focusing on the details that will get our customers really excited, like a wider selection of fun hats, a pterodactyl-shaped gondola ride to the top of the island, and a brand new Gordon Ramsay designed menu at the Cretaceous Cafe.

Unfortunately, I find the thought of teeny-tiny invisible viruses flourishing in almost invisible droplets of water in your breath to be far more terrifying than dog-sized reptiles with pointy sharp teeth. I’d rather the streets were overrun with Cretaceous carnivores — they’d be much more manageable, and the first people they’d eat are those assholes out protesting about stay-at-home orders.

Need to visit my doctor more often

I’m back from my doctor’s visit! It was nothing but good news. The outside walls of the clinic are covered with swarms of chironomid midges!

Everywhere I looked, there they were, clinging to the brickwork. This is one big buffet for spiders that I’ll have to check again later, but I didn’t see many today — just one lone jumping spider hanging about. There has to be more.

Oh, yeah, I’m also fine.

Classic orb

A reader sent this in — I’m envious. I’ve been eyeing various likely sites for webs, haven’t seen any of the orb webs yet. I’m in the land of cobwebs and jumping spiders right now, and haven’t had much of an opportunity to get out and explore yet.

Soon, though. I’ll be fetching my wife in about two weeks, and then it’s a summer of visiting lonely empty places with lots of spiders. Romantic!

I only find out now about this?

I grew up in the Pacific Northwest, and no one ever told me about the Pacific folding trap-door spider. I sure never saw one. But this lucky woman out walking her dog saw one on the sidewalk and — oh what a waste — ran away.

Experts say the spider she spotted is a Pacific folding trap-door spider. It’s not a tarantula, but it is a “tarantuloid” – a related type of arachnid – according to Jaymie Chudiak, general manager of the Victoria Bug Zoo.

“It is the closest thing we have to a tarantula,” Chudiak said. “They are incredibly beautiful, but also very large, so people who do see them go, ‘Oh my gosh, what is that? It’s enormous.’ But they’re actually extremely docile and timid.”

If you want, there’s a picture at the link. It’s beautiful.

I also learned this.

Like tarantulas, there is a commercial market that sells Folding Trapdoor Spiders. Many species in this genus are brown or dark brown. The black, native Pacific Folding Door Trapdoor Spider is commonly sold in the Pacific Northwest as a pet.

“Commonly”? “Commonly”? It is true. I wasted my youth, because I never saw one. Now I want to.

Hoo boy, the Discovery Institute is pathetic

Everyone seems to be “pivoting to video”, including the creationists, so I might as well join in the fun. The Discovery Institute put out a quasi-animated video with a young hipster narrator to promote science denialism — they want to claim that the whale transitional series is bogus, and that all those fossils are just a random jumble of unconnected species that somehow just appeared, and none of them are really intermediates. So I had to expose the flaws in their thinking. Unstylishly, of course.

If I look a little bit squinky-eyed, it’s because I only noticed after recording it that the sun was glaring in through the window to one side. Next time I do one of these, I’d better draw the blinds.

Bring me…a shrubbery!

I made my usual rounds of the house, seeking spiders, today. In particular, I have my eyes on this:

It’s some kind of twiggy bush growing near my house — I have no idea what it is, my resident plant-identifier is off in Colorado, neglecting my needs — but what you can’t see in this, as in all the shrubberies around my house, is that there are delicate lines of silk connecting all the branches. It’s true, I look in my yard with all the newly budded plants around it, and all I see are frames for holding spider silk. I stared at that for about a half hour, possibly making the neighbors wonder if I was already going mental, tracing each branch and every strand of silk, hoping to find the perpetrator.

I did not.

I will be checking regularly throughout this spring, and I’m certain that at some point I will catch them in the act. It’s just a matter of time, and they will be mine.

I did find other spiders on the wall, though. The usual zebra jumpers and asiatic wall jumping spiders…

…but also this mysterious young lady. Curious. She looks a bit like Attulus, but so dark. I see a lot of variation in color, though, so I don’t know.

Then, I struck gold. I found the first Parasteatoda specimen I’ve seen outdoors since last year. She even killed a mosquito for me!

I want you to know, though, that in order take her picture, I had to get down on my knees in the dirt. Then I had to get even lower and lie on my side to get the right angle. I think it’s going to be laundry day.

As usual, the spider photos are tucked away on Instagram, iNaturalist, and Patreon if you want to see them.

This is not a photo of a spider

I wouldn’t do that to you. This is a single line of webbing on a metal signpost.

I wandered around on a walk this afternoon, and while I didn’t find any spiders, I’ve started noticing that everything everywhere is held together with delicate tracings of silk, fueling my new hypothesis that what’s really holding the planet together is the work of spiders.

I haven’t yet found any spider associated with this particular strand of silk, although there were many similar lines — therefore, since it’s invisible and holds all of earth together, it must be Jesus. I’ll keep looking and see if I can get a photo of Him. (Note: more likely to be a Her, and not a vertebrate at all, which leads to some provocative corollaries to my hypothesis.)
